The Surfer Reward example has been completely rewritten.
The main idea is to reward a visitor with X satoshi after he/she visits Y pages, staying on every page no less than Z seconds. Well, you can see it in action even on this page (mouse me to highlight)
Reasonable simple, moderately flexible, ZIP available to download and use on your website. Check it out 😉

Another Micropaiment option has been added cryptoo.me. Simple but powerful. Highly recommended!
Nice feature: when you claim from other cryptoo.me faucets and use your cryptoo.me deposit address, you immediately fund your faucets – useful for newbies, who want to play with own faucet without hustle of bitcoin transfers.
